While Keiji Inafune is perhaps best known as the co-creator of Mega Man, his upcoming project Mighty No. 9 apparently draws more inspiration from Onimusha.
Comparing Mighty No. 9 with his past work on the Mega Man series, Inafune had this to say:
In Onimusha, you had a system where the end user would be put into a scenario where they had to either suck in a soul to get the soul bonus, or attack an oncoming enemy. That risk represented a moment-to-moment gameplay scenario. What we wanted to do with Mighty No. 9 was include an absorption dash, where you can shoot an enemy from afar to make him weak, and dash through him to gain his power. Alternatively, you can be safe, and shoot him until he's dead.
Mighty No. 9 is an upcoming 2D platformer made possible by a successful Kickstarter last year. The game is set to release on a plethora of platformers next year, including the Nintendo Wii U and Nintendo 3DS.
